Definitions
- 1-125 ions are present as a dispersion of Ag 125 I, some of the Ag 125 I will gradually dissolve as the immobilisation reaction progresses thus generating 1-125 iodide ions in solution.
- 1-125 ions m solution may react directly with the oxidised silver (i.e. the Ag + cation) to form Ag 125 I.
- the oxidised silver may react first with bromide ions to form AgBr, followed by ion-exchange of 1-125 iodide for bromide to give Ag 125 I.
- both oxidation of the silver and formation of AgBr will result m removal of 1-125 from the solution phase.
- Some metal halides for example silver halides, are light-sensitive .
- silver halides silver bromide is most light-sensitive, followed by silver chloride and silver iodide respectively.
- One disadvantage of the prior art process of US-A 4323055 for forming silver iodide-coated silver wires was that the light-sensitivity of the silver iodide meant that the process could not be carried out under natural light, but had to be carried out under red light.
- a further significant advantage of the method of the present invention is that it need not be carried out under safe lights but can be carried out under normal room (fluorescent) lights.
